Steven Reid has signed a two-year contract extension at West Brom keeping him at the club until the summer of 2014.
The defender was out of contract at The Hawthorns in the summer, although the club did have the option of keeping him for an extra 12 months.
Roy Hodgson confirmed earlier this month that the club had opened talks with the 31-year-old about extending his stay with the Baggies, having joined from Blackburn in 2010.
The new deal is a reward for the form of Reid, who started 21 Premier League games this season before an ankle injury ended his campaign early.
Sporting and technical director Dan Ashworth said: "We're delighted to have agreed a new contract with Steven.
"He's had a good, solid season and proved he is still more than capable of playing Premier League football.
"He is also a fantastic person to have around the training ground.
"Steven is valued by the club not just because of what he brings to the football field, but also his contribution off it.
"He has an important role to play as we look to establish ourselves as a top-flight club."
